SEPARABLE KEY.

Specification of Letters Patent.

Application filed May 5, 1913.

itateni ed Sept. 23,1913.

serial No. 765,434.

To all whom it may concern .Be it known that I, Myron WV. \Vmnn, a citizen of the United States, and resident of San Diego, county of San Diego, and State of California, have invented certain new and useful Improvements in Separahle Keys, of which the following is a specification.

lriy invention relates to a door key made in parts, one of which remains in the lock while the door is l cried and the other part is removed from the lock and may he carried in the pocket of the user, if desired.

The ohjects of my invention are, first, to provide a key which may he used on either side of the door for locking; the same, and a portion left in the look so that a pass or other key cannot he'inserted in said lock; second, to provide such a key in which the portion left in the door is not readily turned from either side for unlocking the door; third, to provide such a device that is simple, economical of construction, durable and easily operated, and fourth, to provide keys with a plurality of different shaped connecting parts so as to increase the variety of keys.

With these and other ohjects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts as will he hereinafter described in detail and particularly set forth in the appended claims, reference loeingv had to the accompanying drawings and to the characters of reference thereon which form a part of this s peeitication, in which Figure 1 is a side view of one form of my key complete, Fig. 2 is a side View of the part that remains in the door lock when the door is locked, Fig. 3 is an end view thereof showing by dotted lines the position of spring when the door is locked and the handle removed, Fig. 4 is a side elevational view of the part that remains in the door when locked shown in a slightly modified form, Fig. 5 is a fragmentary side view of the handle portion adapted to fit the shank of the door lock portion shown in Fig. l, Fig. 6 is an end view thereof, and Figs. 7 8 and 9 show the same as Figs. 4, 5 and (3 in a slightly modified form.

Similar characters of reference refer to si1'nilar parts throughout the scvc 'al views.

The handle piece 1, look piece 2 and spring, piece 23, constitute the principal parts of my key constructimi.

The lock piece 2 is a pin provided with a flat hlade or hip; 2" on one side. This log 2 may he of various shapes and sizes with parts cut away to [it a variety of locks as the ordinary key is made. It is provided with a collar 2 around the main portion and extending); therefrom for some distance is a square spindle 2", upon the end of which is another collar 2. .l lxtending from this collar 2 is a round spindle 2 with flattened sides or there may he a variety of shaped spindles, a few of which are shown in the different forms shown in the Figs. 2 to 9 inclusive. Upon the square spindle 2 is mounted the spring, 3 which is shaped as shown host in Figs. 2 and I it is douhle with the extended ends coining close together at point ?r" and is provided with a log 2-3" which extends close to the connection piece 2. This spring is adapted to h't tightly around the square piece 2, so that when turned relatively to said piece it will form a spring lock for each quarter revolution of the piece 2. The handle piece 1 is preferahly provided with a loop 1' on its one end similar to the ordinary key and on its other end is provided with a variety of shaped caps adapted to tit the connection pieces 2 of the pieces 2, the shapes being various the same as the shapes of the connection pieces 2 so that a large variety of shapes and forms may he used. This extending; end Il is flat on two sides in each case and provided with a flange the rest of the way around adapted to engage with the log 3 on the spring 2-} when in a certain 1'ela tive position to the piece 3, hut when turned a quarter of the way around the flat surface is adjacent to said loo; 3" and the hair dle piece may be removed, leaving the pieces 2 and 3 in the keyhole of the look.

It will be here noted that the blades 2 show a simple blade for turning the tumhlers of an ordinary look, but. it may he of any shape desired and of various shapes to turn a variety of looks; that the connecting pieces 2 and the conforming portion 1 of the handle piece may be of various shapes for tortional connection, so long as they allow the removal 0f the handle piece when the blade 2 and the spring piece 3 are at right angles to each other; otherwise the handle piece 1 and piece 2 are held together by means of the flange on portion l and,

vention the construction, combination 'and' arrangement substantially as set forth in the appended claims.

It is obvious that with this construction there is provided a key made in two general parts, one of. which remains in the door lock when locked and the other portion is removed and may be carried by the user of the key; that it may be used on either side of the door as desired; that the spring piece 3 will remain downward at all times fitting the keyhole, and the handle piece can only be removed when the blade 2" is turned at right angles thereto or in a horizontal plane and-that in unlocking the door the handle piece must be put in the same position to remove the part 2, which isdone by simply pushing in and turning it one quarter of the way around or until the key blade is down, when the lug 8 engages with the'fiange on the portion l and the key is removed, including the lock piece; that the spring piece 3 mounted tightly on the square port-ion forms a spring lock with each quarter revolution of the piece 2 relatively to said spring piece.

Having thus described my invention, what I claim as new anddesire to secure by Letters Patent, is:

1. In a separable key the combination of a key divided into two parts, and a spring means mounted on one of said parts adapt-- ed to engage and disengage said partswhen in certain relative position on said part.

2. In a separable key the combination of a; handle part, a lock part, a spring mounted on sald lockpart engaging with SZLlCl. handle 3. In a separable key the combination of a pin provided with a lug thereon adapted for turning the lock, said pin portion pro-.

vided with a square portion, a spring mounted on said square portion and a handle portion engaging with sald pin portion provided with oppositely disposed lugs adapted to engage with said spring portion when turned in certainposition to said spring portion, but to be readily disengaged when in other relative positions.

4. In a separable key the combination of for turning a door lock, said pin provided with a'square portion, an extended spring said pin provided with oppositely disposed lugs adapted to engage with said lug on said spring when turned in certain position to said spring, but to be readily disengaged when in other relativepositions f 5. In a separable key the combination of a pin provided with a lug or blade thereon of the conventional kind adapted forturning an ordinary lock, said pin provided with a square portion, a spring mounted on said square portion adapted to lock each quarter turn of said square portion, and a handle part engaging with said pin provided with oppositely disposed lugs adapted to engage with said spring portion ,when turned in certain position to said spring a pin provided with a lug thereon adapted portion, but to be readily disengaged when l in other relative positions.

In testimony whereof, I have hereunto subscribed my name in the presence of two subscribing witnesses.
